Hello

I want to buy the vent louvers to my mustang, but the problem i have making any mod to my car is that here in Mexico we dont have much places that sell anything. Im going to the states the next week (Richardson, Tx) and found a store in which i might buy thelouvers. My question for you guys is it is difficult to install the louvers, do we make holes at the car or what is the procedure to install them.

Also do they are easy to remove, like if my car is at the street a thief can remove it easily ?


Many Thanks
